Generate "All magics..." menu live...

Generate "All magics..." menu live this use 'user_expression' request to ask for the value of 'get_ipython().lsmagic()' and populate the menu with the result. As is, the action need to be triggerd by hand, once the console have appear. Otherwith there is no prompt The logic can certainly also be shortend by using msg.id instead of uuid We should also keep a list of magic that shouldn't be executed without argument (eg: %gui) and don't put them in the menu. or appending '?' at the end
